FOREWORD By Gwen Chisholm Smith Staff Officer Transportation Research Board TCRP Report 137: Improving Pedestrian and Motorist Safety Along Light Rail Transit Align- ments addresses pedestrian and motorist behaviors contributing to light rail transit (LRT) safety and describes mitigating measures available to improve safety along LRT alignments. The report also includes recommendations to facilitate the compilation of accident data in a coordinated and homogeneous manner across LRT systems. Finally, the report provides a catalog of existing and innovative safety devices, safety treatments, and practices to use along LRT alignments. The results of this research may be useful to transit operators, consultants, and state safety oversight agencies. Previous light rail safety related research, including TCRP Report 17: Integration of Light Rail Transit into City Streets, TCRP Report 69: Light Rail Service: Pedestrian and Vehicular Safety, and TCRP Research Results Digest 5: Second Train Coming Warning Sign Demonstra- tion Projects, looked at a number of safety systems, identified safety measures, and proposed safety enhancements--but they did not provide a systematic approach for the evaluation of current measures. New safety issues, or at least the potential for new safety issues, have arisen and need to be evaluated. Additionally, a review of the actual effectiveness of the pro- posed measures identified in the previous research based on actual experience provides before-and-after examples that could affirm or disprove their safety benefits. In addition, it is currently difficult to compile meaningful safety data in a time-efficient manner. Individual transit agencies have conducted localized safety studies on an ad-hoc basis; however, these studies have not been coordinated or conducted following consistent procedures. A system of compiling safety data is needed to enable transit agencies across the country to report comparable safety data. Under TCRP Project A-30, iTRANS Consulting Inc. was asked to develop a framework or template for collecting data to be used to improve pedestrian and motorist safety along light rail transit alignments. To fulfill this project objective, the research team did the fol- lowing: (1) collected, reviewed, and summarized published and unpublished information from U.S. and foreign LRT systems relevant to safety measures, devices, and practices on LRT alignments, including at-grade crossings and stations with enhanced safety for pedes- trians, motor vehicles, and LRT passengers; (2) conducted a survey of U.S. LRT agencies to gather information on the type of data that are collected after an LRT accident (This infor- mation includes a description of the type of accident data provided to the state safety over- sight agency, as well as the accident information provided to FTA and other regulatory agen- cies.); (3) conducted a survey of LRT systems in North America to identify innovative control devices, applications, and unique operating environments and practices related to

light rail safety that have been implemented, including enforcement and educational prac- tices; (4) developed a methodology to perform risk analysis for safety measures at LRT align- ments; and (5) using the information gathered from the data collected, identified success- ful elements and new technologies used to improve light rail safety, described possible factors (including pedestrian and motorist behavior) contributing to LRT safety, and rec- ommended ways to facilitate the compilation of accident data in a coordinated and consis- tent manner across LRT systems.
